Hi, for me, Pentax could change left side mode/WB/ISO wheel to the thingy in style of the one found in Z1P and Z1. It would be just superb for digital camera, as you would always be in shutter priority - even during changing ISO, WB, image quality, you could always back to photographing by just pressing shutter button - no need to turn the wheel to come back to one of exposure modes. And with this one solution many functions could be integrated in one convenient control wheel - no need to create more buttons, which start to confuse you if there are too many of them scattered around camera body. If they returned to known from Z1s hyper exposure modes, then they could back to that too instead of copying thing from Nikon D100 and similar cameras.
